4kq hesitiation

[Nathan Ray]

I accidentally sent this to the marketplace first, so sorry to whoever has 
to read it there.  Yesterday my 4kq started to idle roughly and hesitated 
for several seconds anytime I try to accelerate.  While doing this the motor 
shakes the car pretty hard.  The fuel pump has buzzed for the past few years 
and I suspect that it has finally stopped producing sufficient pressure.  Is 
this typically what happens when a fuel pump goes bad?  Hopefully you guys 
can give me some insight before I go get a pump if that isn't the problem.
Thanks
Nate Ray
